Abstract

A multi-channel wavelength division multiplexed (WDM) transmission system using non-degenerate fourwave mixing (FWM) in a semiconductor optical amplifier (SOA) with spectrum-sliced ASE inputs from a single LED high powered incoherent source is presented. Three incoherent ASE inputs generate twelve SOA output channels, nine of which are FWM generated, and all are modulated at 10 Gb/s after the FWM process to avoid phase-noise limitations. SOA input power saturation characteristics were investigated and eye diagram analysis confirms high-quality transmission for each FWM channel, with an average achievable link length of 63.9 km, proving the validity of the scheme. By decoupling carrier generation from data encoding, this postFWM architecture enables clean performance despite incoherent seeds, offering a low-cost, scalable solution for WDM in access and metro networks and wavelength conversion if required.
